i have a b20/vtec...and i used to have an AEM one piece intake...unfortunatly it sucked up mad water(no place to put the bypass valve)...so i decided to get a j's racing intake...and for anyone that is thinking to buy one or the other...the j's racing intake is by far a better buy, and i have gotten more power out of it then the aem would ever be able to give, AND it wont ever suck water up...also it sounds 10X better then the AEM in vtec...GO J'S racing!!!
